Patent GB-904393-A (GB)
Title: Improvements in air-blast electric circuit breakers
IPC: H01H33/56
Filed: 1960-08-12
Abstract: 904,393. Air-blast switches. ALLMANNA SVENSKA ELEKRISKA A.B. Aug. 12, 1960 [Aug. 13, 1959; May 7, 1960], No. 27932/60. Class 38 (5). In an air-blast switch having a plurality of insulating columns 3 each carrying an extinguishing chamber 1 housing a " breaking gap," the insulating columns and the chambers being filled with compressed air when the switch is opened and closed, the supply of compressed air is limited by throttling means which, when the switch is opened, are opened for a short time to effect rapid refilling of the columns and chambers with compressed air. Thus, in the event of damage to a column or chamber, the loss of compressed air from the rest of the switch is prevented. In the arrangement shown the throttling means each comprise a valve member 8 normally closed by a spring 11 and having a small channel 37 through which compressed air is supplied to the associated column 3. To open the switch a valve 39 is operated to supply compressed air to a pipe 2 connected to the switch operating mechanisms and to supply compressed air to a cylinder containing a piston 44. This piston operates a valve 13 to vent cylinders 10 to atmosphere so that the compressed air acting on pistons 9 opens the valve members 8 to permit a full supply of compressed air to the columns 3 and chambers 1. After a short time the pressures on both sides of the piston 44 are equalized by air passing through a channel 38, so that the valve 13 is restored to the position shown in which compressed air is supplied to the cylinders 10 and the valve members 8 are closed. To permit the switch to be initially filled with compressed air a cock 42 and non-return valves 43 are provided. In an alternative arrangement, Fig. 1 (not shown), provision is made for opening the valve members 8 without air being supplied to the control air pipe 2.

Abstract: 419,841. Reversing-gearing. NAAMLOOZE VENNOOTSCHAP KROMHOUT MOTOREN FABRIEK D. GOEDKOOP JR., 2, Ketelstraat, Amsterdam. Oct. 18, 1933, No. 28873. Convention date, Oct. 18, 1932. [Class 80 (ii).] Relates to reversing-gearing suitable for marine propulsion of the kind in which reversed drive is obtained by holding by a brake 26 the carrier of bevel pinions 5 connecting wheels 3, 4 fast on the driving and driven shafts 1, 2, respectively, and in which on forward drive the gearing is caused to turn solid by a plate clutch, the thrust in which is taken up as tension in a clutch casing or drum 8. The thrust in the plate clutch in this invention is passed on through the central part 13 of a spider 14 carrying the pinions 5 and through both bevel wheels 4, 3 to the end of the drum 8 remote from the clutch plates. There are inner clutch plates 27, 28 feathered on an extending boss 20 of the wheel 4 interleaved with outer plates 17, 16, 15 slidable on bolts 11 carried by the drum 8. The last outer plate 15 abuts against the back of the wheel 4 or against friction pads 29 carried thereby. The back of the wheel 3 abuts against a shaped part of a casing end plate 9. When a cone 25 is slid leftwardly to engage forward drive, levers 23 exert a rightward pull at 24 on the other end cover 10 and a leftward push through studs,21 to the clutch plates. This push passes through all the plates, and through the elements 4, 13, 3 to the end plate 9 and returns as a leftward tension in the whole length of the drum 8 applied to the end plate 10. Thus no external axial thrust is necessary to maintain clutch engagement. Oil collected in gutters at 30, 36, and 40 is returned to the toothed gearing.
